Indlela yokuxazulula umthwalo ophezulu we-VPS? Indlela yokuthuthukisa ukusebenza + umhlahlandlela ophelele wokwandisa inkumbulo ye-CPU

Ingabe i-VPS yakho igcwele kakhulu futhi isizowa?

Iqala ngokulungiselelwa kwe-4-core 16GB, lesi sihloko sihlaziya ngokuningiliziwe indlela yokukhetha inombolo efanelekile yama-CPU cores nenkumbulo, futhi inikeza umhlahlandlela ophelele wokuthuthukisa ukusebenza kwe-VPS.

Kungakhathaliseki ukuthi i-database optimization, ukulungiswa kwesicelo se-PHP noma ukuthuthukiswa kwezingxenyekazi zekhompuyutha, sineziphakamiso ezithile zokukusiza ukuthi uthole isixazululo esingcono kakhulu sokwenza i-VPS yakho isebenze ngokushesha futhi izinze kakhudlwana, futhi sithi sala kahle kumabhodlela okusebenza!

Ngithemba ukuthi lezi zingakusiza, ukuze i-VPS yakho ingabe isaba matasa njenge-kebab stall!

I-VPS ilayishwe kakhulu Mangaki ama-CPU cores nenkumbulo okufanele ithuthukiswe ibe yikhona?

Cabanga ukuthi i-CPU yokucushwa kwe-VPS ingama-cores angu-4 + inkumbulo engu-16GB, hlola top Isimo somthwalo sibucayi Mangaki ama-cores nenkumbulo okufanele asetshenziselwe i-VPS?

kulokho okunikezayo top Uma sibheka okukhiphayo komyalo, umthwalo we-VPS yakho uphakeme kakhulu, nomthwalo omaphakathi ufinyelela ku-54.22 (umzuzu wokugcina ongu-1), 34.14 (imizuzu engu-5 yokugcina), kanye ne-32.00 (imizuzu engu-15 yokugcina).

Lokhu kubonisa ukuthi isistimu yakho ibhekene nokusetshenziswa okuphezulu. I-VPS yakho ine-CPU engu-4-core kanye ne-RAM engu-16GB, kodwa inkumbulo esetshenzisiwe ingu-13,411,120KiB, okuyi-781,120KiB kuphela esetshenziswa njengebhafa.

Ngokusho top Kusukela ekuphumeni komyalo, ungabona ukuthi kunezinqubo ezimbalwa ezidinga izinsiza:

• i-mariadbd (isevisi yedatha ye-MariaDB):Ithatha izinsiza eziningi ze-CPU (143.1%).
• i-memcache:Ithatha inani elithile le-CPU (7.7%).
• Izinqubo eziningi ze-php-cgi:Ngayinye ithatha i-CPU ethile nezinsiza zememori.

Indlela yokuxazulula umthwalo ophezulu we-VPS?

Izixazululo zokulayisha okuphezulu zingabandakanya:

1. Lungiselela isizindalwazi:Uma i-mariadbd ithatha i-CPU eningi, ungase udinge ukuthuthukisa imibuzo yesizindalwazi noma ucabange ukukhulisa izinsiza zeseva yesizindalwazi.
2. Lungiselela izinhlelo zokusebenza ze-PHP:Njengoba kunezinqubo eziningi ze-php-cgi ezithatha i-CPU eningi nenkumbulo, ungase udinge ukwandisa uhlelo lwakho lokusebenza lwe-PHP noma umbhalo ukuze unciphise ukusetshenziswa kwensiza.
3. Khawulela inani lezinqubo:Cabangela ukusebenzisa okuthile okufana ne-nginx's worker_processes noma ukulungiselelwa kwe-PHP-FPM's pm ukukhawulela inani lezinqubo.
4. Isandiso sensiza:Uma ukulungiselelwa kungakafinyeleli izidingo zakho, ungase udinge ukuthuthukisa i-VPS yakho ekucushweni okunamacores amaningi noma i-RAM eyengeziwe.
5. Gada futhi uhlaziye:Sebenzisa amathuluzi okuqapha athuthuke kakhulu ukuze uhlaziye ukusetshenziswa kwensiza yesistimu futhi uhlonze izingqinamba.
6. Ukulinganisa komthwalo:Uma ithrafikhi iyingxenye yenkinga, cabanga ukusebenzisa ukulinganisa kokulayisha ukuze usakaze izicelo kuwo wonke amaseva amaningi.

Ngaphambi kokucabangela ukuthuthukisa i-VPS yakho, kunconywa kakhulu ukuthi uthuthukise uhlelo lwakho nezinhlelo zokusebenza kuqala.

Ukuthuthukisa izinsiza zehadiwe kufanele kwenziwe njengendlela yokugcina futhi kuphela lapho kunqunywa ukuthi ihadiwe yamanje ayikwazi ukulungiselelwa ukuhlangabezana nezidingo.

Ungawubeka kanjani umkhawulo wenqubo ye-VPS?

Lapho ubeka imikhawulo yenqubo, kufanele ucabangele izici ezilandelayo:

• Inombolo yamanje yezinqubo:Udinga umkhawulo wenqubo ozwakalayo ongaphezu kwenani elimaphakathi lezinqubo ukuze ugweme ukuthikameza ukusebenza okuvamile.
• Izidingo zesistimu nesicelo:Qonda ukuthi zingaki izinqubo isistimu yakho nezinhlelo zokusebenza ngokuvamile ezidinga ukusebenza.
• Ukusetshenziswa kwensiza:Qapha i-CPU nokusetshenziswa kwenkumbulo ukuze unqume imikhawulo yenqubo ephusile futhi ugweme ukukhathala kwensiza.
  Uma kubhekwa inombolo yamanje yezinqubo kuseva yakho, kuyanconywa ukuthi ungasethi umkhawulo wenqubo ubephansi kakhulu.

Umkhawulo oweqile, njengokuthi 50 noma 100 womkhawulo othambile kanye no-100 noma 200 womkhawulo oqinile, ungase ufaneleke kakhulu. Ungalungisa lokhu ngokusekelwe ekulayisheni nasekusebenzeni kweseva yakho.

Uma unquma ukushintsha imikhawulo yenqubo, qapha ukusebenza kweseva yakho eduze futhi ulungele ukubuyisela emuva izinguquko uma kwenzeka kuba nokucisha. Ngesikhathi esifanayo, cabanga ukuthuthukisa uhlelo lokusebenza nokulungiselelwa kwesistimu ukuze unciphise inani lezinqubo ezingadingekile.

KWLinuxuhlelo, ungadlula /etc/security/limits.conf Izilungiselelo zefayela zikhawulela inani lamafayela avuliwe, ifomethi imi kanje:

Imikhawulo yenqubo yokucabangela isethiwe:

I-VPS ithuthukisiwe isuka ku-4-core 16GB yaya ohlelweni oluhle lokucushwa

Kuyaqashelwa ukuthi kunezinqubo ezingaba ngu-500 ezisebenza kakhulu, ngakho-ke kuyadingeka yini ukuthuthukisa ukucushwa kweseva? Ikuphi ukucushwa kweseva okunconyiwe ukuthi kuthuthukiswe kukho?

Uma ucabanga ukuthi uhlelo lwakho lokusebenza ludinga ukusebenzisa inombolo enkulu yezinqubo ngesikhathi esisodwa, futhi ufuna ukuqinisekisa ukuthi isistimu inezinsiza ezanele zokusingatha umthwalo omkhulu, nazi iziphakamiso ezithile:

• Inombolo yama-CPU cores:Thuthukela ku-CPU enama-cores angu-8, 16, noma ngaphezulu, kuye ngokuthi uhlelo lwakho lokusebenza lungazuza yini ekucushweni okuningi.
• usayizi wenkumbulo:Nyusa imemori ibe ngu-32GB, 64GB, noma ngaphezulu, kuye ngezidingo zememori yohlelo lwakho lokusebenza kanye nenani lezinqubo ozenzayo.
• Izinsiza ezengeziwe:Cabangela ukungeza izinsiza ezengeziwe, njengeseva yesizindalwazi esizinikele noma isilinganisi sokulayisha, ukuze uthuthukise ukusebenza nokuthembeka kukonke.

Khumbula ukuthi ukuthuthukisa ukucushwa kwehadiwe yakho akuyona impendulo ezinkingeni zokusebenza. Qiniseka ukuthi ikhodi yakho yohlelo lokusebenza, imibuzo yesizindalwazi, nokulungiselelwa kweseva kuthuthukisiwe ukuze kusetshenziswe ngokugcwele izinsiza zehadiwe ezengeziwe.
